This is the error message I get each time in the unit test
Please I need help.
You have to understand matrix multiplication because the size of your matrices getting multiplied is not right, this is what the error tells you and also you have many posts similar to this in the forum:
Gent thank you very much.
I understand matrix multiplication. I think my problem is python coding. I have not done any course on computer programming
Well then you should take some online python courses I think, “python for everybody” in coursera is a pretty good one!
Thank you once again. I will do my best
